Definitions
- the invention relates to a method for binding particulate waste, such as dust, metal waste, fibers, paper waste or the like, to solids.
- Particulate wastes such as Filter dusts, which are particularly common in large quantities when cleaning flue gases, are e.g. bound with cement and water.
- Metal dusts e.g. Grinding dusts are very difficult to use. In particular, metal dusts can no longer be smelted due to the small particle size. The same applies to other metal waste, e.g. small metal shavings.
- Fibers such as Asbestos fibers that are generated as waste can only be transported with great safety precautions and only partially recycled.
- Paper waste such as secret documents, old paper money withdrawn from circulation, check forms, securities or the like. should usually be made unusable immediately without transport. While such paper waste was usually burned in the past, this is often encountered today due to environmental regulations. Toxic exhaust gases are also generated due to the special printer color.
- DE-A-2.402.976, DE-A-2.444.420 and DE-A-2.539.195 describe a method for recycling i.a. thermoplastic waste known to be processed into a new material.
- This plastic waste is mixed with more than 50 percent by weight fillers in a mixer at elevated temperatures.
- the fillers can be wood waste, asbestos, peat, sulfur, silica, sand, graphite, metal chips, ashes from waste incineration plants, waste from thermosetting plastics or the like. act.
- the plastic is crushed in particle form so that it can be mixed with the fillers in the mixer.
- the plastic is mixed with the other parts, it is converted into the plastic or liquid state by applying heat, the parts are mixed and connected under pressure.
- the fillers which may also be provided with a coating, are introduced with the plastic waste into a mixer, where they are heated up to 400 ° C., depending on the plastic, and discharged from the mixer as a quasi-homogeneous paste.
- This paste can e.g. also subjected to a further process step after cooling, such as extrusion, extrusion, calendering, pressing, injection molding or granulation.
- the shaping of the material in this last process step can also be carried out if the material still has a pasty consistency at elevated temperature.
- the forming can take place under low pressures.
- the pasty mass can be pressed through a calibration nozzle and extruded into a strand or a plate.
- the wood chips are coated in a vacuum, i.e. the chips are pre-dried before they come into contact with the plastic waste.
- Other fillers can also be used under a gas atmosphere.
- the material can with a low pressure of some kg / cm2 to 30 kg / cm2 can be formed by pressing or by injection molding.
- the material has a density of 0.8 kg / ltr to 2.5 kg / ltr.
- a commercially available kneading mixer or an agitator with a heated housing can be used as a mixer for this known method.
- This known method for recycling plastic waste is not only machine-intensive, but also very energy-intensive, i.e. not very cheap.
- EP-A-0.262.083 it is known to produce a solid fuel from industrial production residues, which may or may not be comminuted, mixed with one another and pressed into a desired shape, and which consists of cellulosic material, in particular wood and / or paper, and There is polyethylene. During the pressing, the moisture present in the mixture is evaporated and the steam is removed.
- This fuel has a high calorific value and a high density for transport reasons. It is environmentally friendly and universally applicable and can be stored indefinitely even with changing weather conditions.
- the invention has for its object to provide a method with which particulate wastes such as dusts, metal wastes, fibers, paper wastes or the like can be bound cheaper and a better, in particular reusable product can be obtained.
- Plastic waste is generally understood to mean organic carbon-containing liquids or solids. This can be solid plastic waste of any kind, but also paint sludge or other sticky, especially organic sludge.
- the particulate wastes, dusts, metal wastes, fibers, paper wastes or the like, and the plastic wastes such as organic carbon-containing liquids or solids or the like are fed into the hopper of a screw press.
- the components entered are intimately mixed in the screw press by the revolving screw (s) and pressed very strongly in the process.
- the pressure in the mixture can be up to 100 bar.
- the temperature in the screw press can be easily controlled in accordance with the plastic waste used.
- the mixture is kneaded in the screw press until essentially all of the air, i.e. both that present in the particulate waste and the additional air added, and the air which has entered the screw press during filling, is removed.
- Liquids in particular thickened waste liquids, can also be added to the mixture in the screw press.
- liquids containing pollutants can be fed into the screw press. Due to the high heat in the screw press, the liquid evaporates, especially water. The evaporating liquid, especially if it is also harmful, can be collected and condensed when escaping from the screw press. The solid components are kneaded into the mixture.
- filter dusts from flue gas cleaning systems are used as particulate waste. These are integrated into the plastic so that they no longer come into contact with the environment. However, care should be taken to ensure that the plastic is corrosion-resistant.
- the weight fraction of the plastic waste in the solid mixture is up to 30%, in particular approximately 15%.
- the screw press no premixer or the like. upstream, it is recommended that the plastic waste is added to the mixture in granular form.
- the granules can have a diameter of 10 mm to 40 mm.
- Film waste have an area of 2 mm * 2 mm. This results in an even mixture in the material emerging from the screw press.
- the product emerging from the screw press which can be in the form of bars or pellets, can withstand pressures of up to 400 kg / cm2 and, depending on the material used, has a density of up to 1.8 kg / ltr and more.
- the pellets or bars can have a cross section of e.g. Have 60 * 60 mm2.
- pellets or bars can be stored as such. But they can also be combined into larger blocks and sprayed with plastic. As such, they can also e.g. can be used as building materials.
- pellets or rods also contain metallic materials, they can also be smelted in a metallurgical plant.
- the non-metallic substances burn due to the high temperatures prevailing there.
- the heat generated can be used for the smelting process.
- the screw press can e.g. have a training as described in WO-A-83 / 03.999, DE-A-3.714.508, DE-A-3.714. 509 and DE-A-3.714.518. It is a screw press with two screws arranged parallel to each other.
- the particulate waste arrives e.g. from a storage container onto a conveyor belt on which they are weighed. Depending on the weight of this waste and the dosage ratio, the plastic waste is dosed onto the conveyor belt. Both types of waste are introduced together into the feed hopper of the screw press.
